a Detection of high densities of specific k-mers associated with SC (mapped to 50 kb bins of DM v4.03; columns) across various potato genotypes (rows) suggests the identification of one common haplotype involved in SC at a distal locus on chromosome 12. Row 4 represents the Sli locus of M6. This suggests that one haplotype identical-by-state to Sli is also present in potato varieties. Genomic sequences from well-known SC diploids and varieties (Hardigan et al. 2017) were retrieved from public archives. b Pedigree relationships between genotypes positive for the SC haplotype. Year of market release is shown for varieties. The first (putative) SC ancestor of each clone was annotated together with the generation at which it was found. Blue boxes: clone bearing a complete SC candidate region; teal box: clone bearing an incomplete SC candidate region; white boxes: clones not tested in this study. Relatives are connected with arrows. First generation relatives—solid arrows; 2nd generation relatives—dashed arrows; 3rd generation relatives—dashed-dotted arrows; 6th generation relative—dotted arrow.
